CAT 469-2033 BEARING

CAT 469-2033 (4692033) is a Caterpillar radial ball bearing (non-tapered roller bearing), suitable for the rotating connections of handrails/levers in CAT power stairs and aerial work platforms. It provides smooth rotation and wear-resistant support under low loads. The following are the core information:

Core Technical Parameters
Item Details
Part Model: CAT 469-2033 (4692033) Radial Ball Bearing (Suitable for light-load rotating connections, such as levers and handrail shafts)

Core Materials: Inner ring/outer ring: Carbon steel (compliant with SAE 1045), hardened to HRC 58–62; Balls: GCr15 chromium steel, surface Ra≤0.2 μm; Cage: Stamped low-carbon steel, to prevent ball misalignment

Key Dimensions: Inner diameter 25.4 mm (1 in), outer diameter 42 mm, width 9 mm, ball diameter 6.35 mm, number of balls 10, radial clearance C3 (0.005–0.012 mm), compatible journal tolerance h6 (0–-0.013 mm), bearing housing tolerance H7 (0–+0.018 mm)
Single weight: Approx. 0.045 kg (0.1 lb)
Compatible models: CAT Powered Stairway, aerial work platform (e.g., 450E/450F) handrail pivots, lever joints, for low-load, high-frequency rotating parts Cat®…
Operating fit: Dynamic radial load 3.2 kN, limiting speed 12000 rpm (grease lubrication), operating temperature -20℃ to +100℃, compatible with general-purpose lithium-based grease (NLGI 2)
Core functions and structural features: Integral ball bearing: Inner ring/outer ring/balls/cage integrated, easy to install, suitable for light-load rotating conditions in confined spaces.

Low-friction design: Steel ball point contact, low coefficient of friction (f=0.001–0.002), low rotational resistance, and improved operational flexibility.

Standard clearance fit: C3 radial clearance compensates for temperature changes and installation errors, prevents jamming, and ensures smooth rotation.

Lightweight structure: Weighing only 0.045 kg, it is suitable for weight-sensitive parts such as handles and joysticks without adding extra load.

Installation and maintenance points:

Installation specifications: Clean the journal and bearing housing. The journal surface Ra≤0.8 μm, free of scratches; use a clearance fit (0.002–0.008 mm) with the shaft and a transition fit with the bearing housing.

Use a plastic hammer or socket to evenly tap the inner ring end face during installation to avoid deformation of the outer ring due to stress, ensuring a tight fit with the shaft shoulder.

After assembly, apply a small amount of lithium-based grease, filling 1/3 of the bearing’s internal space to prevent dry friction.

Maintenance Recommendations

Inspect every 500 working hours: Check for pitting and wear on the steel balls/raceways, and for abnormal noises during rotation. Replace immediately if radial clearance is >0.02 mm.

Avoid confusion with similar models such as 469-2034. Verify the inner diameter/outer diameter/width. The inner diameter of 469-2033 is fixed at 25.4 mm.

Regularly clean impurities from the shaft area to prevent foreign objects from entering the bearing and causing abnormal wear.
